Eriogonum kennedyi var. purpusii

Higher Taxonomy
Family: PolygonaceaeView DescriptionDichotomous Key
Habit: Annual to shrub [tree]. Stem: nodes swollen or not. Leaf: simple, basal or cauline, generally alternate; ocreae present or 0, generally scarious, persistent or not. Inflorescence: flower clusters in axillary to terminal cyme-, panicle-, raceme-, spike-, umbel- or head-like arrangements, entire inflorescence or main inflorescence branches generally subtended by bracts ("inflorescence bracts"); peduncles present or 0; flower clusters in Eriogoneae-Eriogonoideae subtended by involucre of >= 1 free or +- fused, sometimes awn-tipped bracts ("involucre bracts") or, in Polygonoideae and rarely in Eriogonoideae, not (if bracts completely fused, involucre "tubular"); pedicels in Eriogoneae each often subtended by 2 free, transparent, linear bractlets or in Polygonoideae all subtended by 2+ fused, membranous, wide bractlets. Flower: generally bisexual, small, 1--200 per node; perianth parts 2--6, generally in 2 whorls, free or basally fused, generally petal-like, often +- concave adaxially, often darker at midvein, often turning +- red or +- brown in age; stamens [1]3 or 6--9 in 2 whorls; ovary superior, 1-chambered, ovule 1, styles 1--3. Fruit: achenes, included in or exserted from perianth, generally 3-angled, ovoid or elliptic, generally glabrous.
Genera In Family: 48 genera, +- 1200 species: worldwide, especially northern temperate; some cultivated for food (Coccoloba, sea-grape; Fagopyrum, Rheum, Rumex) or ornamental (Antigonon, lovechain; Coccoloba; Muehlenbeckia; Persicaria; Polygonum), a few timbered (Coccoloba; Triplaris). Several (Emex; Fallopia; Persicaria; Polygonum; Rumex) are weeds. Note: Treatment of genera in Eriogonoideae based on monographic work of James L. Reveal. Involucre number throughout is number (1--many) per ultimate grouping, at tips of ultimate branches; flower number is per flower cluster or involucre, unless otherwise stated. Fagopyrum esculentum Moench not naturalized, considered an historical waif (or garden weed +- presently), therefore not treated.

Genus: EriogonumView DescriptionDichotomous Key

Habit: Annual to shrub, matted or not. Stem: prostrate to erect, occasionally 0, glabrous or hairy, occasionally glandular. Leaf: basal, sheathing (on stem above basal, beneath other, +- non-sheathing cauline), or cauline, alternate, opposite, or whorled; blades linear to +- round, generally longer than wide, margins flat, wavy, or rolled under; ocreae 0. Inflorescence: variable, glabrous or hairy, occasionally glandular; peduncles 0 or erect to reflexed (pointed down); involucres 1 or in clusters, tubular, glabrous or hairy, teeth generally 4--10, awns 0. Flower: (2)6--100(200), with a stalk-like base ("flower stipe" or "stipe") or not; perianth generally white to red or yellow, glabrous or hairy, occasionally glandular, lobes 6, generally entire; stamens 9. Fruit: generally brown or black, generally obconic, glabrous or hairy; embryo curved or straight.
Etymology: (Greek: woolly knees, for hairy nodes of 1st sp. named) Note: One of largest genera in California; stem in descriptions refers to the main stem(s), not branches of inflorescence. A perennial herb allied to Eriogonum austrinum (S. Stokes) Reveal and Eriogonum moranii Reveal of east-central Baja California, with spreading (rather than reflexed or erect) involucres on peduncles < 2 mm, occurring in DMtns (Bristol, Granite mountains), has been known for nearly 25 years yet remains undescribed. Eriogonum puberulum moved to Johanneshowellia.

Species: Eriogonum kennedyiView Description 

Habit: Perennial mat. Stem: scape-like, (0.5)1.5--4.5(5) dm, glabrous or generally tomentose. Leaf: basal or sheathing; blades 0.2--1(1.2) cm, 0.05--0.4 cm wide, tomentose, margins occasionally rolled under. Inflorescence: head-like, 0.4--1 cm diam; peduncles 0; involucres 3--7, 1.5--4 mm, 1--3.5 mm wide, rigid, glabrous or tomentose. Flower: 1.5--4 mm, glabrous; perianth white to pink or rose, lobes oblanceolate to elliptic or obovate to +- oval. Fruit: 1.8--4 mm, glabrous.

Eriogonum kennedyi S. Watson var. purpusii (Brandegee) Reveal

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
